What is PUL?
PUL is Polyurethane Laminate
PUL is a polyester fabric that has been laminated (coated) with polyurethane on the inside as the water resistant layer.
PUL is the water-resistant our layer used with reusable nappies.
PUL is breathable so is not waterproof, which is why you need good absorbency to prevent leaks and wicking.
